Former co-host of MythBusters Adam Savage has described his recent adventures in New Zealand as "mind-bendingly cool and amazing".
Savage, an American industrial designer and television personality, landed in the country last Friday for a "special project" with Tested website creators Will Smith and Norman Chan.
While the purpose of their trip has been kept secret - with the stars stating on their website that they "can't disclose exactly what we're working on" - they have spoken enthusiastically about "an amazing adventure" they had with director Peter Jackson.
In a video launched on Youtube on Tuesday, Savage, Smith and Chan excitedly talk about the opportunity to fly in Jackson's World War I fighter planes over the weekend.
The trio were taken to an unknown airfield on Sunday where Savage was treated to a flight in a Royal Aircraft Factory R.E.8 British two-seat biplane.
